Description

Abstract:

This is a high resolution survey (1:5,000 scale dataset) describing mapped vegetation communities for the Rapid Creek catchment area (within the City of Darwin, Northern Territory).
(Vegetation Unit - A reasonably homogeneous part of the land surface, distinct from surrounding terrain with constant properties in landform and vegetation)

The original survey was conducted in 1994. This dataset represents the vegetation on the ground at the time of the survey and reflects the data and methods used to create the mapped polygons. The dataset has been revised in 2015 to include community descriptions but has not been updated to reflect the vegetation on the ground. The Darwin Remnant Vegetation Survey is considered a more up-to-date representation of vegetation for this area.

Data Quality

Lineage:Original map unit boundaries delineated from aerial photographs and stereoscope interpretation. Map units transferred to topographic map sheets via a mapograph. Original maps were hardcopy only. With the advent of geographic information systems polygons were digitised by rectifying the original hard copy maps.
Map unit boundaries derived using hard copy aerial photography and stereoscope, satellite imagery (post 1993), geological and topographic maps. Field data (site data) described and classified according to national standards at the time of capture.
Map unit polygons collected via geographic information system (ArcGIS/MapInfo). Additional attributes attached to map units unique to individual surveys.

Positional Accuracy:Polygon Data (1998 - 2013): Map unit boundaries transferred from aerial photographs to topographic maps, using the best available topographic mapping at the time (generally 1:100 000) via a mapograph. Level of accuracy depends on the number of control points on individual aerial photographs. Control points include creek lines, cadastre and other topographic features. Depending on the nature of the landscape (the number of control points), positional accuracy may vary. Positional accuracy generally considered moderate to high.

Point Data (1990 - 1997): Site point coordinates collected from a geographic positioning system with general accuracy of within 100m. Selective availability during this time prevented increased accuracy.

Attribute Accuracy:Attributes assigned according to the dominant feature. Descriptive attributes for each vegetation community have been added to all polygons.

Logical Consistency:GIS editing tools were used to rectify all overshoots and undershoots in line work. Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.

Completeness:Complete
